Abstract: To obtain a small and high performance damper mechanism which reduces pressure pulsation in low pressure-side fuel in the high pressure fuel pump in a high pressure fuel supply system or a high pressure fuel pump provided with the small and high performance damper mechanism.Two metal diaphragms are welded together over the entire circumference to obtain a metal diaphragm assembly (also referred to as “double metal diaphragm damper”). The whole or part of the portion of the metal diaphragm assembly other than the weld (for example, the portion inside the weld) is clamped by a pressing member and thereby the assembly is secured in a housing enclosure. The housing enclosure may be formed integrally with the body of a high pressure pump.

Abstract: The present invention provides an axial plunger pump which does not need bellows by restricting fuel to a cylinder bore configuring a pump portion and by lubricating the other portion with oil. The high pressure fuel pump comprises a plunger reciprocating according to a shaking movement of a swash plate, a cylinder block forming a pump chamber together with the plunger, and a sealing member provided between the plunger and a cylinder bore for sealing oil leaked from the pump chamber to a chamber surrounding the pump chamber, wherein oil in the oil chamber is supplied from the outside of the high pressure fuel pump.

Abstract: In a conventional high-pressure fuel pump, the interference fit part between a plunger and a retainer comes loose with time due to environmental factors and this reduces the clearance between the retainer and a tappet more than necessity, resulting in increase in the contact face pressure between the plunger and a cylinder when a side force acts on the plunger, which causes seizure between the plunger and the cylinder. In this invention, a protrusion protruding toward the tappet is provided around the through-hole for press-fitting the plunger, the through-hole provided in the center portion of the retainer. Since the clearance between the retainer and the tappet can sufficiently be kept even if the joint between the retainer and the plunger comes loose, the seizure between the plunger and the cylinder and the breakage of the plunger are less likely to occur even if the side force acts on the retainer.
Abstract translation: 在传统的高压燃料泵中，由于环境因素，柱塞和保持器之间的过盈配合部分随时间而松动，并且这比必要性减小了保持器和挺杆之间的间隙，导致接触面压力增加 当侧向力作用在柱塞上时，在柱塞和气缸之间，这引起柱塞和气缸之间的卡塞。 在本发明中，在贯通孔周围设置有朝向挺杆突出的突出部，用于压入柱塞，设置在保持器的中心部分的通孔。 由于保持器和柱塞之间的间隙即使保持器和柱塞之间的接头松动也能够保持保持器和挺杆之间的间隙，所以即使侧向力也不会发生柱塞与气缸之间的咬合以及柱塞的破损 作用在保持架上。
